The coliseum will be taken over by "Night Storm Party."
It's a traveling entertainment dance club for high school students.
"First time we've had it here at the coliseum, so it'll be interesting to see how it all turns out," said Coliseum Marketing Manger Jenna Wilson.
The party's goal is to give youth the feeling of being a big city club, without the alcohol.
"They have a confetti cannon, and lasers and a whole bunch of stuff," said Wilson. "So it will be a fun night for teens here in Bloomington."
Dozens of students R.S.V.Ped to the bash on Facebook.
It's an indicator some say shows they're looking for new activities.
"It's a way for the kids to have fun here. Listen to music, do some dancing," said Wilson. " It keeps them away from drinking."
Meantime Daddios nightclub has been aiming for the same goal.
It wants to hold teen nights at its bar on Tuesdays.
But getting city approval isn't as easy.
"It is unusual for a tavern which has a legal restriction...nobody under 21," explained Bloomington Mayor Steve Stockton.
After establishing safety guidelines, the city has agreed to let Daddios hold a teen night trial run, in hopes of giving youth a fun place to hang.
"We've committed to at least two of these," said Stockton.
If all goes well at each establishment, the city plans to continue giving teens an opportunity to enjoy being young.
Night Storm Party at U.S. Cellular Coliseum goes till eleven tonight.
The facility has stepped up staffing and hired police patrols for the event.
